Abstract
The utility model relates to a muffler for a vehicle air conditioner in vehicle air conditioner fittings, which comprises an upper shell with a liquid outlet hole and a lower shell with a liquid inlet hole. The upper shell and the lower shell are combined into a muffling shell. The inside of the muffling shell is transversely provided with a muffling clapboard. The muffling clapboard divides the muffling shell into an upper cavity and a lower cavity. The muffling clapboard is provided with through holes. The muffler for the vehicle air conditioner is welded in a low-voltage tube of an air conditioning pipe and takes the obvious muffling effect.
Description
Technical field
The utility model belongs to the air conditioner parts technical field, is specifically related to the used for automobile air conditioning muffler in a kind of air conditioning for automobiles accessory.
Background technology
The noise of automotive air-conditioning system is because the vibrations that parts such as compressor, evaporimeter, condenser produce cause that the noise of automotive air-conditioning system can cause that driver and crew's mood is unhappy, influences comfort of drivers and passengers.Automobile can be along with the increase of service life and mileage number under the normal condition, it is more and more that noise also can become, the air conditioning for automobiles pipeline that connects parts such as automobile air conditioner compressor, evaporimeter, condenser is the vital part that reduces noise, and muffler is the critical component of noise reduction in the air conditioning for automobiles pipeline.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides a kind of used for automobile air conditioning muffler of simple in structure, easily manufactured and good muffling effect.
The realization the technical solution of the utility model is as follows:
The used for automobile air conditioning muffler, comprise the upper shell with fluid hole, the lower house of inlet opening, upper shell, lower house are combined into sound attenuation, be horizontally arranged with sound gobo in the described sound attenuation, sound gobo is divided into upper cavity, lower chamber with sound attenuation, and described sound gobo is provided with through hole.
Be provided with turbulated tube in the described through hole.
Being arranged on the sound gobo of described through hole off-centre.
Eccentric distance between described through hole center and the sound gobo center is 12mm.Refrigerant process setting-up eccentricity distance is the turbulated tube of 12mm, and change flows to, and changes flow, and refrigerant is fully turbulent in the confined space of upper shell and sound gobo and lower house and sound gobo formation, thereby reaches the effect that abates the noise.
The sound attenuation inwall that described upper shell and lower house are combined into is provided with the mounting groove that sound gobo is installed, and like this when sound gobo is installed, just sound gobo is stuck in the mounting groove and positions.
The corner of described upper shell, lower house adopts arc transition, has both helped the moulding of die cavity, plays the effect that abates the noise again.
The thickness of described sound gobo is 2mm.
Adopt such scheme, the used for automobile air conditioning muffler satisfies the standard-required of TL82316, whole part can under the pressure of 85bar, keep 3 minutes indeformable, burst pressure is greater than 137bar.When frequency was 2Hz, amplitude was ± 12.5mm, and test temperature is-30 ± 1 ℃, and total vibration number is 20000 alternations, and muffler is without any leakage.The utility model is welded in the air-conditioning pipe low-voltage tube, and the erasure effect that plays is fairly obvious.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a cutaway view of the present utility model;
Fig. 3 is the zoomed-in view of D among Fig. 2;
In the accompanying drawing, 1 is fluid hole, and 2 is upper shell, and 3 is inlet opening, and 4 is lower house, and 5 is sound gobo, and 6 is turbulated tube, and 7 is circular arc, and 8 is mounting groove.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Shown in Fig. 1-3, the used for automobile air conditioning muffler, comprise the upper shell 2 with fluid hole 1, the lower house 4 of inlet opening 3, upper shell 2, lower house 4 are combined into sound attenuation, be horizontally arranged with sound gobo 5 in the sound attenuation, sound gobo 5 is divided into upper cavity, lower chamber with sound attenuation, and sound gobo is provided with through hole.Be provided with turbulated tube 6 in the through hole.Being arranged on the sound gobo of through hole off-centre.Eccentric distance between through hole center and the sound gobo center is 12mm.The sound attenuation inwall that upper shell and lower house are combined into is provided with the mounting groove 8 that sound gobo is installed.The corner of upper shell, lower house adopts circular arc 7 transition.The thickness of sound gobo is 2mm.
Each part of used for automobile air conditioning muffler all adopts aluminum material to make, and when the utility model is assembled, earlier turbulated tube and sound gobo is carried out aluminium soldering, connects to be integral, and guarantees that the eccentric distance d of turbulated tube and sound gobo is 12mm; The interface of upper shell, lower house is reserved the wide breach of 2mm, so just sound gobo is blocked the location, by argon arc welding upper shell and lower house is welded into the integral body of a sealing this moment; In order to reach the requirement of burst pressure, the wall thickness of upper shell, lower house is designed to 2.5mm greater than 137bar.
When using the utility model, inlet opening is connected with air-conditioning pipe aluminum pipe respectively with fluid hole, refrigerant enters lower house through inlet opening, it is big that diameter becomes suddenly, turbulated tube by minor diameter changes flow velocity inflow lower house again, flows out through fluid hole again, and wherein the flow direction through eccentric turbulated tube changes, make refrigerant turbulent flow in muffler, reach the effect that abates the noise.The result is simple for this muffler, and is easily manufactured, and the erasure effect of generation is remarkable, is widely used in the air-conditioning pipe of various vehicles, and erasure effect is good.
